Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Climatological analysis for hygrothermal performance evaluation: Mid-rise wood (Report to research consortium for wood and wood-hybrid mid-rise buildings)

Mid-rise wood constructions: hygrothermal modelling and analysis (Report to research consortium for wood and wood-hybrid mid-rise buildings)

The objective of the Hygrothermal Modelling and Analysis Task was to estimate the risk of moisture damage to the structural elements of a mid-rise wood building. Specifically, the objective was to characterize the risk of moisture damage to the load-bearing wall components of two wall constructions specified in \u201cMID-RISE WOOD CONSTRUCTIONS \u2013 Specifications of Mid-rise Envelopes for Hygrothermal Assessment\u201d Client Report A1-100035-03.1 [ ] due to trapped construction moisture.Peer reviewed: NoNRC publication: Ye
